I found this image awhile ago while browsing around and I thought I should share it here as well. Maybe some graphic designers who uses Adobe Photoshop and Adobe Illustrator are not more into these Keyboard Shortcuts. I myself as a person is a keyboard-guy not just in Photoshop, Illustrator or in any software that I use. Even when I’m typing in Microsoft Word or Excel, I love using keyboard shortcuts. I find it more easy and fast to work on things when using keyboard shortcuts.
I know this is just some basic shortcuts but it can be a good start to help you out. I myself got some bunch of shortcuts that includes CTRL, Alt and Tab keys which I find hard to list down here one by one. Maybe when I find time to do so. For the mean time, have fun with these Adobe Photoshop and Adobe Illustrator keyboard shortcuts!
